Ok so im new to the site, and I know next to nothing about Porsches. I work ata BMW/ Lamborghini dealership, and we received 2 trade- ins this week; a 2004 carrera, and a 2006 carrera 4. I was curious if anyone could give me a list of the factory performance upgrades for the 2004, because the car was incredibly fast, but supposedly had no extra performance packages, just the sport exhaust. Ive heard of the X50, and F77, but I wanted to know if someone could give me a listall of them, or whereI could find one easily,and what each one can specifically do. Thanks a lot.

 

Hi I would only list 3 basic Options as strictly meeting the criteria of Performance Upgrades:
XLF SportsExhaust (small power and torque gain)
X51 Performance Kit raises Engine Power/Torque from 320 BHP to 345 BHP
X74 Lowered Sports Suspension with 18" Wheels Lowered by 30mm
030 Lowered Sports Suspension. 17" Wheels Lowered by 10mm
X73 Lowered Sports Suspension, 17" Wheels Lowered by 20mm
